I "Applicatin July 23, 1932.0 sr;a1No.` 6`24,1s6f QF v-sclaims. f (131.1984220) vvThis invention-relates to .reciprocating conveyors known in the art as .shaker chutes and has particular'reference toaguide frame therefor.;

' Shaker chutes as used in mining operationsy andfor various other purposes usually comprise a unit composed of ai series Avof metal VVtrough sections connected end to end Aand suitablyA supported at intervals by ball frames so as to be y capable of reciprocation by a powerdevice.y The power device may be of any preferred crsdesired character and in the present instance is adaptedl to be connected to one of the trough sections, termed the drive section'.V Y v During reciprocation forcesarisewhich tend tov shift the unit both verticallyand sidewise and it vis necessary to provide means "to'prevent excessive sidewise and verticalV shifting of the unit.

The presenty invention `contemplates -a new and improved guide frame for shaker chutes which is adapted not only to support the drive trough section in such a manner as to permit reciprocation thereof but is adapted to prevent excessive vertical and sidewse shifting. f I

' Another object of this invention '1s the provision of anew and improved shaker lchute -including a drive trough section and a guideframe for supporting ther-opposite end portions thereof i'n such a manner as to-prevent iexcessiv'e. vertical and sidewise shifting of sa1d trough se`ction.

Another object of vthis invention isv the fpro.

In the construction shown in Figs'. 4,'5 andV 6 the projecting ,portions 40 of ythe channel 32 underlie the upper flanges 14 of the channels 12 and are adapted to cooperate directly with the upper` ilanges 14 to prevent excessive yvertical shifting of the trough section relativel to the base frame A. Obviously, if` desired, a Wear plate may be provided on the under surfaces of the upper flanges 14 of channels l2 in a manner similar to 2. In the construction shown in Figs. 4-6 inclusive, however,- excessivel sidevvise shifting of the drive trough section'lB is prevented by cooperating elements connected respectively with the base Y e the construction illustrated more clearlyin Fig. Which may be mounted on suitable-*rollerA bearframe .A and the trough ksection B and in this'- .Welded as at 56 to said flanges and to the web 38 ofthe channel and depends belovv.` the. lower edge Y portions of theaflanges between the; upwardly'arrrangedlflanges 58 of; angle'v members ilisecured as byrivets..V 62,` tor thejchannels; 1l of vthe baseV frame.

Y y

From the above description it is believed that the constructionand operation vof the guide frame of the present invention will be fully apparent to those skilled in the art. Obviously excessive vertical shifting of the trough section relative to the base frame is eliminated either by contact of the projecting portions 40 of the channel 32with the Wear plates 42 or by direct contact of the projecting portions 40 Aand the upper flanges 14 of the channelsk 12 or the upper flanges 72 of the Z-sections 70. 'Sidewise shifting of the trough section B relative to the base frame is reduced to a minimum in the construction illustrated in Figs. 1'-3 inclusive by contact of the wear.

plates 42 and 44, which wearplatesalso serve as a means for guiding the trough section the direction of reciprocation. In the 'instance shown in Figs. 48 inclusive excessive sidewise shifting of the trough section is eliminated by the co- Y loperating-members 56 and60.

The drawings herein' illustrate several embodiments of the invention but it is to be understood that these drawings are for illustrative purposes only and various changes inY the form and lproportionsof the device may be made within the scope of the appended claims without departing from the spirit of the invention.
